METHOD FOR MANUFACTURING AMOLED PIXEL DRIVE CIRCUIT

WIPO Patent Application WO/2018/049744

A1

Provided is a method for manufacturing an AMOLED pixel drive circuit. An ES-type drive thin film transistor (T2) and a BCE-type switch thin film transistor (T1) are manufactured by only retaining a second insulating layer covering a second active region (42) to serve as an etching stopper layer (5); the BCE-type switch thin film transistor (T1) has a relatively small parasitic capacitance, which can reduce the RC effect, and facilitates the control of an alternating-current data signal; and the ES-type drive thin film transistor (T2) has excellent device characteristics, which can provide a stable current for an OLED and ensure the stability and uniformity of the light emission of the OLED.
